This PMD isn't usable without an external library that I don't believe we ship.  Do you intend to package that library containing the mlx5_glue symbol?

Hi Neil,

As I understand it, the glue lib stuff is part of DPDK RPM itself, it's there so that the pmd
will attempt to use only the provided functionality by the existing rdma-core.

we tried over FC31 by building rdma-core v29 and dpdk 20.05 from sources and didn't see any issue.

ah, ok, apologies, I see it now, I'll go ahead and enable this today
